# Run Continuous Integration (CI) Tests on Modal ## Unit testing Unit test strategy created like in [This example repo](https://github.com/modal-labs/ci-on-modal) ## Usage All commands below are run from the root of the repository (this directory). _Note_: I removed modal-decorators from pricer.ci-module to be able to run unit tests. ### Run tests remotely on Modal ```bash modal run pricer.ci::pytest ``` On the first execution, the [container image](https://modal.com/docs/guide/custom-container) for your application will be built. This image will be cached on Modal and only rebuilt if one of its dependencies, like the `requirements.txt` file, changes. ### Debug tests running remotely To debug the tests, you can open a shell in the exact same environment that the tests are run in: ```bash modal shell pricer.ci::pytest ``` _Note_: On the Modal worker, the `pytest` command is run from the home directory, `/root`, which contains the `tests` folder, but the `modal shell` command will drop you at the top of the filesystem, `/`. To run test: ```bash cd root pytest ```
